The elation faded eventually, curling up in the back of Kakashi's ribcage like a warm secret he could grab hold of, when he needed to. It was replaced by boredom. A lot of boredom.

It was a nasty secret, known by most war veterans, that boredom could be even worse than torture. You knew where you stood with torture, even if that was upside down with your head in a water barrel. Torture kept your attention engaged. Boredom was just... draining.

He stripped the new bandage off his right hand, bracing himself for another seal, and blinked when he found the wound scrubbed and ointment-painted, but otherwise untouched. No ink. And as unpleasant as it was to realize the medic had been able to do all that without waking him, that tended hand was a good sign. Somewhere, serious diplomacy was happening.

Kakashi re-wrapped the bandages and got to his feet again. Scouted the cell for changes.

The first missing thing he noticed was Genma's tea set. Someone, probably the assistant, had also taken the empty water bottles, the dirty plates, and the used med kit. The lamp was still there, along with the cards, which had been tidied back into a neat deck. There was also a new med-kit, bigger looking then the last one, a stack of ration bars, a few more bottles of water, and a roll of toilet paper. There was even a fresh toothbrush and tube of toothpaste.

Kakashi raised his eyebrows.

"You forgot the kitchen sink," he said, just to hear a voice, and almost punched himself in the head. Talking to Iwa was not a habit he needed to cultivate.

Twelve hours until Fujita, Sugimoto had promised, which was more than enough time for Genma to be well on his way home, and for Kakashi to go entirely stir-crazy. He gave himself a rough little shake, feeling every dark-bruised ache ripple through exhausted muscles, and knew the best course of action was just to wear himself out more. Until he couldn't worry.

Water first, then a ration bar and bathroom break. Then painkillers, if there were any in that kit, and he could damn well brush his teeth. Then he needed to warm up, limber up, and do whatever exercises his body could manage until he fell over.

Sufficiently armed with a plan, Kakashi wrapped a tight mental fist around that one warm thought, and set to work.
